transmission shift kits?

I have been looking at things I could do to make my transmission shift better and also last longer. What exactly does a shift kit do? Fix the problems that never got fixed by the manufacturer? Also, what kind of shift kit should i get and would a dealer install it? I would like to make my transmission shift better and I have heard something about the corvette servo?

Every manufacturer has different shift kits that have different purposes and operate differently. It depends on the tranny you got and how you use it. Go to the website of a company called TransGo. They make the best shift kits in my opinion. And for your servo question, a corvette servo is supposed to make your tranny shift firmer and more positive and shift at different points than your stock servo. Jet Performance sells an aftermarket servo that does the same thing.

The term "Shift Kit" is a trade mark of TransGo similar to the word Coke or Kleenex. It's used rather loosely and not all valve body kits are the same. I agree TransGo makes the best valve body kit. The kits are designed to address wear problems in the valve body which cause driveability problems and can set trouble codes. Usually a TransGo kit AND a Corvette Servo will make most street trucks shift too hard. My advice is to do the valve body kit first and drive the truck. You will love how it shifts. If after you do that and you still want a firmer shift the slap in a Corvette Servo. The servo can be added without dropping the pan.

If I'm not mistaken you should have the 4L60E. But find a good reputable tranny shop near you and just tell them what truck you have and they will know your transmission and will know exactly the shift kit you need. The shop I had mine put in did it for $250 total. And he said he never rebuilds a 4L60E without putting the TransGo shift kit in.

I'm gonna dig this up from the grave. Locally I can get the Transgo kit for $65, vs the $155 its listed for from Monster Transmissions. I'll probably end up going and picking it up weds/thursday to hopefully solve my 1-2 shift issue. But before that I would like a little insight on how it shifts after wards.. Is it still kinda soft? I understand firm is better for the life of the transmission but I would still like it to be relatively gentle for the ladies :lol:
